Like What, is Lignum Vitae Considered a Type of Hardwood or Softwood?
Lignum vitae (also known as guaiacum) is a unique species of tree that often confuses people when it comes to its wood classification. While it’s commonly referred to as a hardwood, some experts argue it’s actually a softwood. So, what’s the truth?
- Hardwoods are typically derived from deciduous trees, like oak or maple, that have broad leaves and a sapwood phase. They contain specific vessel elements and vary in color.
- Softwoods, on the other hand, are derived from coniferous trees, like pine or spruce, with needle-like leaves. Softwoods have erected tracheids and are usually lighter in color.
Lignum vitae, however, falls in a gray area. Its wood combines characteristics from both categories. Some argue it’s a hardwood due to the following reasons: + It has a broad, leathery leaf rather than needle-like ones like softwoods. + Lignum vitae is an evergreen tree, which is typical of deciduous hardwoods. + When cut, its wood often displays the characteristic ring-porous structure of hardwoods.
Conversely, lignum vitae displays some softwood-like traits: + Its wood is often composed of pertified tracheids, which resemble softwood’s erect tracheids. + Lignum vitae is a conifer, and its wood tends to be lighter in color compared to other hardwoods.
So, is lignum vitae a hardwood or softwood? The answer is, it’s neither exclusively one nor the other.
